BRIGHTSOLAR:



Use Jump start method

jonescosmos:


Because your Lithium battery pack needs to sense battery voltage before starting to charge, It can't help you when it sees 0V from the battery cells (0v Because your BMS has shut you off due to over DOD).

So, to wake up your Battery Pack, You need to Jump start the battery just like you do to your car. But bear in mind that you have a 24v battery pack.
Get a 24V external Battery Charger or An Adjustable DC Power Supply or even 2pcs of 12v Batteries that are charged up, Set the readings to about 27V 10A, Hook up the terminals Negative to Negative and Positive to Positive Terminals of the Charger and Battery respectively.

If your BMS is inbuilt you might need to open the Battery Box because the terminals you have access to outside the box are P- and B+, and you need to hook up your external DC power supply to B- and B+.

Once you do this and certisfying other Input conditions from your Inverter, Mains and Solar Panel sources, etc, your Battery should resume charging, then unhook the external power sources you applied earlier.

If this did not help, then there might have been a fault in your BMS.

I hope this helps. Cheers

I just read a couple of comments where people are asking for where to switch to or concentrate on because it makes you more money. Well I would say that despite the new or modern day nomenclatures that has evolved in computations eg, AI, Coding, CyberSecurity, etc, You must know the basics in any field you are to venture into.

I am where I am today because I have had a practical hands on experience with equipments like: Alcatel, Ericsson, Huawei, TP-Link, DLink, Juniper, NEC, Nokia, Ciena, ZTE, Zycel, Orinoco, Magnums, WAVELAN, Synoptics, Kalpana, Mitsubishi, Meraki, Belkin, Fortinet, Sophos, Cyberoam, SonicWall, Calix, Aruba, Aris, Avaya, Cisco, Motorola, Ubiquiti, CommScope, Control4, EnGenius and the list goes on.

So imaging me and someone without these experiences in a classroom to study CyberSecurity because he has been told that it makes you more money. Or someone who had just graduated from the University and has been told to focus on CyberSecurity because that's where the money is now. I leave you to be the judge.

This is a dry (AGM or GEL) cell battery.

I disagree with your submission. Both transformer and transformerless inverters use transformers, just different kinds. The transformer based inverters uses low frequency transformers while the transformerless uses high frequency transformers.

You can't have an inverter without a transformer.

dacool1:


You want to connect a 3000w inverter to a 100ah battery. Be ready to replace the battery in 2 weeks except you don't load beyond 100watts

Herdamorlar:

Thank you. I just want to power my tv, one ox fan and 5 5watt bulb.
I attached the pictures of the back of the tv and the fan. What advice will you give on this because I don't have much to get more batteries at this time though my plan is to increase the battery every 2months.
Also do I need to use solar controller when charging using only electricity can't from the inverter?

bassdow:
if you studied Electronics, or have background knowledge of such, or even did a little research, you would have known better.


why you think most electronics that used to be BULKy, are now much portable ?

mank1234:


Sorry sir. You can have.
They are so many technology behind transformerless designs.
Some employ HF transformer, some don't.

The essence of the HF transformer and accompanying circuitry is to get 340Vdc, the bus voltage and not to invert (DC to AC). The inversion is done from 340dc and does not need transformer.

So many circuits design exist for stepping up to 340Vdc without the need for HF transformer.

bassdow:

unfortunately, I most times, know what I am saying.

as a Kid, I destroyed and REPaired lots of things. in fact I was likely to be found in electrician's workShop, on my way home from school.of course that was because those things INTERESTs me.

Don't want to say Nigeria happened to most of Us.

Anyway along the line, I developed interest in Computers, and moved around from Computer enginerring TO web design TO Programming To Server admin.

you can't compare when you are engaged in things you're PASSIONATE about, and when you not.

But when you said what You said above, I choose to be 100% sure of what I am say so I quickly asked Aunty Google.com and here's the response - https://www.google.com/search?q=why+do+some+inverters+not+have+transformers AND https://www.google.com/search?q=inverters+without+transformers


As I am now, I easily could StepUp or StepDown voltages and current any how I want without touching a transformer. I only responded just so others who might not know, don't get misInformed

Obnoxious2001:
Please I need suggestions and opinion.

I have this 24v 5.12kw blue carbon lithium battery, that has been drained. The problem now is it has refused to come up.

I have tried using nepa to charge via the inverter , it not waking up, the solar panels too is not working as well...

How do I solve this problem?
Am thing of using an external 24v automatic low voltage disconnect switch to prevent further occurrence in the future, but I have no idea if such system is available.

Beside the inverter is a transformer based hybrid inverter with 100mppt controller.

I can't send image Now because of nairaland palava.

Senior men please come to my aid

incogni2o:


Its likely due to.you using an.hybrid inverter.

A Blue Carbon battery I installed have also been drained about 3 times now.

I think its a bit lazy for the company to.allow the battery go so low before triggering it off

Inverter charges it via generator and it comes up back.

Get a non hybrid inverter to charge it.

its under warranty though, I could assist you how to return it to be checked

How do I reach you?

brightk:
what happens to a low voltage disconnect. Your inverter should be able to disconnect your battery @ a particular voltage set on it.

@litaninja

Let me correct one phrase.

You know networking inside out, should replace the phase that are into networking which I used earlier.


Everything you said up there is valid.

I started by fixing PCs ( hardware) to software to running networks to supplying software to enterprises to architecting complete solutions from scratch incorporating software, hardware and consultancy.

Before I sell a solution, I actually personally play with it and have a working knowledge of the same.

My point is that knowing the basics and knowing them well is non-negotiable.

I use cybersecurity to get in some doors, but I am versed in several aspects of IT and I keep learning. My biggest grossing deal wasn't a cybersecurity deal, but cybersecurity opened the doors for me.

When I started, I bought books on subjects as diverse as open source intelligence techniques, database security, website security, web hacking, networking, windows server administration, computer evidence collection and preservation, Oracle hacking and devoured them, Official Certified Ethical Hacker also.

When these certifications came out, I bought the Official Study Guides books: Certified Wireless Security Professional (CWSP) and Certified Wireless Network Administrator(CWNP).

You need a foundation without which you cannot understand certain concepts. Money does not just appear from nowhere.

incogni2o:


are you saying all inverters are equipped with that feature.

I guess the inverter i had should have same feature, but the voltage range didn't sync properly.

could also be that the battery already protected itself before the inverter did

olopan:
Only those with ideas and understanding will appreciate the wealth of knowledge shared in this post and the prerequisite conversation, that alone sef is enough to get you kicked in the right direction.

Is anyone doing this in Nigeria?

Tracking the sun makes solar panels more efficient on land and water

htps://www.youtube.com/watch?v=sAvXSDqbwDg

olopan:
Short answer is NO!

Ordinary fixed rooftop of top equipment is problem for some due to cost, not to talk of solar tracking array, the reality is that i don't see it being economical solution here in Nigeria, my POV

olopan:
This is what I call painstaking troubleshooting, I am not vast in knowledge of computer but I took on myself to know a bit if this and a bit of that when It comes to I.T

I told a friend one time that the quickest way to gather knowledge and experience is by working with the big players, because there are always new toys to play with at one point which you may not be exposed to if working for yourself.

As a rule of thumb, I avoid certain things that would run me into trouble with computers.

BTW have you ever gotten off of a ransomware before?

Speaking of the value of knowing your stuff inside out.

I decided to update the BIOS of my main laptop on Saturday morning. It turned out to be the biggest mistake of my life. I bricked my primary workhorse and had to literally cancel all my schedule for Saturday and Sunday.

I have been updating BIOS all my life. But this one went south. The laptop would not come on again. To be more specific, it would turn on, but only into BIOS. It would not boot into windows. I tried every trick in the world same thing. I downloaded and created a USB based Windows Boot disk, but it would not load. I downloaded recovery ISOs and used them to create a USB stick that can allow me access the system, no luck.

I then assumed I have a bad USB stick and went to a repair man and he gave me a his own, same thing. Guy was stumped, referred me to someone else who was busy. I went home, kept trying all of Saturday and all of Sunday then luck smiled on me towards evening.

Then something occured to me. As a matter of practice and principle, I try to duplicate how enterprise networks are run at home. It means that I standardized on a particular laptop brand (Lenovo), a particular series of that laptop and that I have several of such laptops at home. I have Thinkpads X series several generations. I have more than one of each generation. X240, X250 and X260

So I said, when I bought this laptop, I swapped out the 250gb SSD for the 1TB SSD from my retired laptop. What would happen if I put back that original 250gb SSD. I tried it and the laptop would come on. So, the problem was with the drive and not the motherboard.

I took it out and returned the 1TB SSD same thing.

I then recalled that they said that X240 and X250 are literally the same internally. So I took out my X250 that I rarely use from storage and it would not come on, the power button would blink and make some noises and then go off. I removed the external battery, same thing. I removed the internal battery, same thing. I disconnected the BIOS battery, reconnected it, reinstalled the internal and external batteries and it came to life. I then removed the SSD that came with the X250 and inserted my 1TB SSD and it roared to life.

If I did not know my onions, I would never have resolved this at home and all by myself.

This story also illustrates for those IT guys who have never operated in an enterprise environment why enterprises always standardize infrastructure. It makes troubleshooting a lot easier. It also explains why you must duplicate the enterprise environment if you want to relate well with your peers inside.

In my days as a hardware and software guy. I was not that guy who fixed a bad PC by formatting it. I never did so. I always repaired the OS. I was very adept at those tools. Which guy would you prefer? A guy that does the easy fix or the guy who tried to understand what went wrong and then fixed it. Who knows the technology better? Who would you want in your corner when you got into IT trouble? I did not mind how long it took.

Even before repairing, I would use Antivirus Boot CDs to throughly disinfect the system because the primary cause of those failures was infection from human error. I would even replace the corrupted operating system files.

That quest to understand the underlying technology and understand how things work and fix the problem instead of just refreshing everything made me extremely knowledgeable of operating systems and led me to such tools like Winternals amongst others. Knowledge that I have sadly rarely ever used since I switched camp. Winternals was so good that Microsoft ended up buying the company and absorbing its founders, I can never forget Mark Russinovich. How much sadness I felt when Microsoft said they would discontinue that line of products. How many hardware and software guys knew that such tools existed? Their solution was to get pirated CDs and reinstall Windows. I never did that.

Neither can I forget The PC Upgrade & Maintenance Guide by Mark Minasi.

In the event that that had to be done, I would extract all the license keys from the installed software before ever formatting. So that the user would not lose his or her investments. I invested so much and found out that private individuals cannot pay for the labor that I put in. They were always willing to pay for hardware but never for the brains that did the work.

I would also save the user's data. I would ransack all corners of the hard drive and I would even take notes of where I got what data from so that at the end of the day, when I was done, the PC would be the same as it was before the trouble.

Then I plotted my pivot from that sort of business and thank God I did. Where I am today and where I was then is literally as different as the night is as different from day.
